Agreed on the sizing issue. I also use Giro because of my shape. My helmet is from 1998 when i bought my first helmet. Pre MIPS and everything else. I bought it when i realized I was going too fast not to have a helmet... I like the idea of the built in visor, but not sure about fogging and such in the midwest. We get sleet, rain, humidity in Michigan similar to you fellows over the border from me.
